8. Nephrodiam paiicijugum Jenman, Jouni. Bol. 1S86: 270; Dryopteris chartacea 

 C. Chr. Ind. 257 — Jamaica, Sherring. 



On this see Maxon Contr. H. S. Nat. Herb. 10: 489. I believe that the 

 type-specimen of it is at Kew, and I have seen it. It is sterile and undeter- 

 minable. It is not improbable that Jenman was right in considering it a 

 young plant of D. oligophylla. 



Subgenus 8. LcptOgramma J. Smith emend. C. Chr. 

 Biolog. Arbejder tilegnede Eug. Warming pag. 82. 1911. 



A small group, in America represented by three species. I confine it to 

 include the species of Gymnogramme § Leptogramtna of Syn. Fil. only having more 

 or less soft-hairy lamina, oblong to linear, exindusiate sori and setose sporangia. 

 The lamina is not or slightly narrowed downwards, the rhizome generally long- 

 creeping, at apex furnished with few hairy scales. The hairs of most species are 

 long, thin, pluricellular. In general habit and venation the species resemble 

 mostly species of Cyclosonis, thus the American D. pilosa and D. dasyphylla, while 

 the third D. polypodioides comes very near to species of Goniopteris, but I have not 

 found stellate or forked hairs, which constantly are to be found in species of 

 Goniopteris. — The typical species of Leptogvamma is the common D. africana 

 (Desv. ) C. Chr. (Gymn. tolta Schlecht.) from Africa and Asia. 



Key.
